PAPER RECEPTACLE.

Application filed December My invention relates to receptacles made froma folded paper blank, and one of the objects of the invention is theprovision of a receptacle having a superior means for of fecting theclosure of the cover flaps. Another object is the provision of areceptacle such as the well known oyster pail in which means areprovided for drawing the folded sides together to secure the snugclosing of the cover flaps and the consequent bracing of the structure.

My invention possesses other objects and features of advantage, some ofwhich, with the foregoing, will be set forth in theIfol t is to beunderstood that I do not limit myself to the showing made by the saiddescription as I may adopt variant'forms of my invention within thescope of the claims.

Broadly considered my invention comprises a receptacle formed from asingle blank of paper, by folding so that the material lying between theadjacent lateral sides of the folded receptacle is turned back in twooverlapping folds on each of its two opposite sides. These overlappingfolds which are each of double thickness not only stiffen thereceptacle, but form the mounting for the wire bail or handle. The blankof paper is of such shape that when itis folded to form the receptacle,a cover flap is formed on each upper edge and a tab on the outer layerof each overlapping fold extends above the upper edge of the receptaclea distance equal to one-half of the width of the 'receptacle at the topbetween the tabs. When the blank is folded the two tabs on each'side arecontiguous and coincident as to outline.

Preferably a flexible metal tongue is secured to the outer of one of thepairs of tabs while an elongated aperture to receive the tongue isformed in both the opposite tabs. When the tabs are bent toward eachother over the closed cover flaps, and the tongue passed thru theopposite apertured tabs and bent back, the effect is to draw theopposite sides of the receptacle strongly to gether upon the enclosedcover flaps, producing a very snug and neat closure, and a rigid strongpackage.

spective of a receptacle showing a modified form of fastener. of amodified form of blank.

Referring first to Fig. 1 the blank comprlses a bottom area 2, side wallareas 3, and end wall areas 4t. End wall cover flaps 6 and side wallcover flaps 7 extend integrally from the end and side wall areas respectively. The areas 8P9 lying between each lateral wall and adjacentlateral end 'walls are creased on the diagonal line 10 when thereceptacle is formed, resulting as shown in Fig. 2, in overlappingfolds.

Extending from each area 8-9 on one side are tabs 11 and 12 respectivelyof a length substantially equal to one-half the distance between theupper edges of the side walls of the completed receptacle. These tabsare both provided with apertures 13; Similarly extending from the areas8-9 on the other side are tabs 14 and 15, to one of which, 15, aflexible metallic tongue 17 is secured by any suitable means.

The position of the tabs and the propertions of the blank are such thatwhen the blank is folded into the form shown in Fig. 2, the aperturedtabs 11 and 12 lie coincidentally, the apertures registering; while onthe opposite side the two tabs 14 and are similarly positioned, theouter one 15 bean ing the flexible tongue 17. It is to be noted that ineach case, the tab extends upwardly from the outer layer of the foldedareas 8-9, with which it is associated. A bail or handle 18 is securedin the lapping folds in the usual way.

lVith the closing of the cover flaps 6 and 7', the tabs may be benttoward each other to permit the tongue 17 to be passed thru the aperture13 in both the opposite tabs. 95

The bending back of the tongue tends to draw the tabs together and sincethe tabs are integral extensions of the outer layers of the folds on theside walls, such folds are drawn snugly in against the cover flaps mak-100 ing not only an exceedingly tight closure, but one of trimappearance, since the gapping of the sides is prevented. The drawing inof the sides into firin, engagement with the cover flaps in the mannerexplained me also results in a package of greater rigidity and strength.It will be observed that the companion tab to the tab bearing thetongue, that is tab 14, is not assigned any particular function in theforegoing. The tab is how- 110 Fig. 6 is a plan view ever smoothed downfiat under the overlying tongued tab 15, and tends, when the outer tabis drawn down tightly over it, to pull in the connected fold and secureit firmly against the cover flaps. If desired the tongue may be securedto both tabs 14 and 15. However it is found that the holes will pull outof both apertured tabs about as easily as the tongue will tear away fromthe single tab.

Referring now to Fig. 4: If desired, both pairs of tabs 21 and 22 may beapertured in the blank, and subsequent to the folding of the blank, aflexible tongue 23 looped thru one pair of tabs. This arrangement ismechanically desirable since it results in an evenly distributed pull bythe bent tongue on all four of the tabs. If commercially practicable,the half bent tongues may be supplied loose and inserted in theapertured tabs and bent flat at the time of closing the receptacle.

The second fastener is however open to obvious objections, and thereforeI prefer in many respects the structure shown in Fig. 5, in which bothpairs of tabs are apertured and the tongue 26 is secured to the uppercover flap 7 in a central position, and with the ends slightly bent upas shown, so as to be readily engageable in the apertures of the tabs.Because of the connection of the two pairs of tabs by means alsoconnected to the outer cover flap, this receptacle is particularly rigidwhen closed.

If desired, the blank, as shown in Fig. 6, may be formed with tabs 28and 29 extending from one of the areas 8 and 9 respectively on eachside, each pair of tabs being symmetrical with respect to the diagonalcrease line 10.

I claim:

1. A receptacle having oppositely disposed sides in each of which a foldcomprising two layers of material extends from both lateral edges to lapat the center of the upper edge, the outer layer only of each fold oneach side being integrally extended in coincident separate tabs attachedonly at their bases, and means separately stressing each of saidoppositely disposed separate tabs for drawing together and securing thesides of the receptacle.

2. A blank for a paper receptacle comprising a rectangular area for thebottom, areas for the sides, areas between the side areas to be foldedagainst oppositely disposed sides when the receptacle is formed, an areafor a cover flap adjoining each side area, and oppositely disposedintegral extensions from said folded areas to form tabs attached only attheir bases wherewith the sides of the receptacle may be drawn snuglytogether and the cover flaps secured in closed position.

3. A blank for a paper receptacle comprising a rectangular area for thebottom, areas for the sides, areas between the side areas to be foldedagainst oppositely disposed sides when the receptacle is formed, an areafor a cover flap adjoining each side area, and integral extensions fromsaid folded areas sub stantially one-half the width of the bottom areain length and forming tabs attached only at their bases, wherewith thesides of the receptacle may be drawn together and the cover flapssecured in closed position.

4:. A paper receptacle having opposite sides each provided with a tab, apair of inner cover flaps, a pair of outer cover flaps, and a flexibletongue attached intermediate its ends to one of the cover flaps andengageable in the tabs. 7

5. A paper receptacle having oppositely disposed sides comprisinglapping folds, the outer layers of the folds on each side beingintegrally extended and apertured to form separate twin tabs havingcoincident slots, a pair of inner cover flaps, a pair of outer coverflaps foldable across the inner flaps, and a flexible tongue attachedintermediate its ends to one of the cover flaps and engageable in theslots of each pair of tabs whereby the sides of the receptacle may bedrawn snugly together and the cover flaps secured in closed position.

In testimony whereof, I have hereunto set my hand.
